웹 계층 개발챕터 강의를 진행하고 있는 수강생입니다.문득 궁금한점이 생겨 질문 남기게되었습니다.코드를 작성하고 서버를 재실행하면 기존에 db에 넣어둔 데이터가 다 날아가고 없어지는게 서비스로직에 달려있는 @Transactional 어노테이션 때문인가요?테스트코드에서의 @Trasactional 어노테이션의 경우 테스트데이터의 경우 테스트만 진행하고 테스트된 데이터는 db에 반영을 하지 않기위해서(Rollback) 사용한다고 알고있습니다.그래서 원래 코드에서도 반영이 되지않는 이유가 서비스로직에 포함된 트랜잭션 어노테이션 때문인지 궁금하여 질문드립니다.

junit5 사용해서 회원 가입 작성하는데 코드 똑같이 작성했는데 오류가 나고 실행이 되지 않습니다.

테스트용 데이터를 추가하기 위해 아래와 같은코드를 만들었습니다.@Component @RequiredArgsConstructor public class TestDataInit { private final ItemService itemService; private final ItemRepository itemRepository; /** * 테스트용 데이터 추가 */ @PostConstruct public void init() { itemService.saveItem(new Book("김영한","츨핀시한빛")); itemService.saveItem(new Book("호날두","출판사멩구")); //오류 발생// itemRepository.save(new Book("a","출판사a")); itemRepository.save(new Book("b","출판사b")); } }한번은 itemService를 이용하여 값을 넣었고 다른 한번은 itemRepository를 이용하여 값을 넣었습니다.제 단순한 생각으로는 '어차피 itemService는 itemRepository에 바로 위임을하니 바로 itemRepository로 저장하자' 여서 실행했더니localhost에서 연결을 거부했습니다. 오류가 나왔습니다.<질문>왜 itemRepository로 저장하면 안되고 itemService로만 저장해야 데이터가 추가되는 지 궁금합니다.

현재 섹션5까지 수강 완료한 상태인데 계속 Fail이 발생합니다 ㅠㅠ처음엔 됐었는데 갑자기 안되더라구영 ㅠㅠ 검색을 해봐도 뭐가 문제인지 파악하기 힘들어서 질문 드립니다!어떻게 해결하면 좋을까요? 

안녕하세요실전! 스프링부트와 JPA 활용 1편 강의를 수강 중인데요.섹션6 주문도메인 개발 중 '주문, 주문상품 엔티티 개발' 강의에서 08:13쯤에 OrderItem에도 상태가 필요하다고 하셨는데 여기서 상태값은 무엇을 말하시는 걸까요?OrderStatus.CANCLE처럼 Enum형식의 상태값을 모아놓은 필드를 말씀하시는 건가요? 맞다면 어떤 상태값이 OrderItem에 들어갈수 있을까요? 주문취소 같은 건 Order에 들어가있고 어떤 값이 필요한지 모르겠습니다. 그리고 바로 그 말씀에 뒤이어 부모 상태로 참고가 가능하다고 하셨는데 어떤 부모의 상태를 말씀하시는 건지 모르겠습니다. 답변 부탁 드립니다.

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

C:\study\jpashop\jpashop\src\main\java\jpabook\jpashop\JpashopApplication.java:10: error: <identifier> expected hello.setData("hello"); 이런 에러가 뜨는데 원인이 무엇일까요..?

boiler plate가 설치된 폴더경로가 지정된 상태에서npm run dev를 입력했고 아래와 같은 오류가 뜹니다npm ERR! Missing script: "dev"npm ERR!npm ERR! To see a list of scripts, run:npm ERR! npm runnpm ERR! A complete log of this run can be found in:npm ERR! C:\Users\user\AppData\Local\npm-cache\_logs\2023-08-17T13_33_04_142Z-debug.logconcerently 도 설치했고 package.json에 아래 처럼스크립트 dev 설정도 잘 되어 있는데 왜 에러가 뜨는건가요 "scripts": { "start": "node server/index.js", "backend": "nodemon server/index.js", "frontend": "npm run start --prefix client", "dev": "concurrently \"npm run backend\" \"npm run start --prefix client\"" }, 

위의 그림과 같이 오류가 발생하는데, 이유를 모르겠어요.. 어떻게 해결해야 할까요? jsconfig.json 파일 안에 include 를 작성하기 전, 뷰를 설치할 때 기본적으로 작성된 코드가 있는 것들을 모두 지우고 영상 강의대로 진행했습니다. 지워진 코드는 아래와 같습니다. // "compilerOptions": { // "target": "es5", // "module": "esnext", // "baseUrl": "./", // "moduleResolution": "node", // "paths": { // "@/*": [ // "src/*" // ] // }, // "lib": [ // "esnext", // "dom", // "dom.iterable", // "scripthost" // ] // }

안녕하십니까 영한님!!!잘만 되던 테스트코드가 어느 순간 아래와 같은 오류가 발생합니다. 해결방법들을 찾아보고 시도해보았지만 해결되지 않아 맨 아래에 구글 드라이브 코드 링크 남겨드립니다. java.lang.IllegalStateException: Failed to load ApplicationContext for

안녕하세요스프링부트와 JPA 활용1 중 섹션1. 프로젝트 생성 강의를 듣고 있는데요.13:04 부분에 플러그인 롬복을 설치하시는데 앞쪽에서 스프링부트 스타터에서 롬복을 받고 빌드를 했는데 플러그인을 따로 설치해주어야 하는 이유가 뭔가요?빌드한 롬복과 플러그인에서 설치하는 롬복은 무슨 차이인지 어떻게 활용되는지 궁금합니다.

"따라하며 배우는 리액트, 파이어베이스"이 강의를 리뉴얼 예정이라고 하셨는데언제 완성이 될지 일정을 알 수 있을까요? 

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

(예/아니오)[질문 내용]생성 메서드를 만드는 경우는 본인이 정하는 걸까요 .. ?item 생성 할 때처럼 간단한 경우는 생성메서드를 만들지 않고 orderItem 생성 시와 같이 복잡한 코드의 경우에만 미리 생성 메서드를 만들어 놓는건지 어떤 경우에 생성 메서드를 만들어 놓는지 강의를 봐도 감이 안 잡혀서요 ..어떤 경우에 생성 메서드를 사용하는 것이 좋은 경우인지 설명해주실 수 있을까용 ..추가로 orderitem을 생성하는 createOrderItem 메서드를 만들고 createOrder시에 createOrderItem으로 생성한 orderItem을 사용하는 걸까요 ? 혹 뒷부분 강의에 해당 내용이 나온다면 이 부분은 답변 생략해주셔도 됩니다 .!
